Overview

Humanin is a small peptide encoded in mitochondrial DNA (a cousin of MOTS-c) with broad cytoprotective effects. Research links it to protection of neurons, improved insulin sensitivity, and reduced cell death under stress, making it a longevity candidate.

How it’s thought to work

  • Protects cells from apoptosis (programmed death) under stress.
  • Improves insulin sensitivity and modulates metabolic and inflammatory pathways.

Researched uses

  • Neuroprotection and healthy-aging research
  • Metabolic and cardiovascular studies

Reconstitution

Often a 5 mg vial. 5 mg with 2 mL water = 2.5 mg/mL, so 250 mcg = 10 units on a U-100 syringe.

Humanin dosage calculator

The calculator below is pre-filled with Humanin’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.

📋 In plain English

Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 20 doses of 250 mcg. For each dose, draw 10 units into a 100-unit insulin syringe.
